Subject: [PATCH 6/6] dmaengine: txx9dmac: simplify getting .drvdata
Date:   Sun, 22 Apr 2018 11:14:14 +0200
Message-Id: <20180422091415.7587-7-wsa+renesas@sang-engineering.com>
In-Reply-To: <20180422091415.7587-1-wsa+renesas@sang-engineering.com>
References: <20180422091415.7587-1-wsa+renesas@sang-engineering.com>

Precedence: bulk

We should get drvdata from struct device directly. Going via
platform_device is an unneeded step back and forth.
